Bangla Calendar

I'm looking for a qualified freelancer to create a Bangla Calendar in digital format. The design I'm hoping for is a traditional Bangla Calendar that contains both Bangla and international holidays. I need a calendar that can be accessed digitally, so preferably something like an app that can be easily accessed on a phone, tablet or computer. I'm open to suggestions with regards to the format for presenting the calendar, so if you have any ideas or know of specific software that could be used to produce this, I'd love to hear them. I'm looking for a clean and professional design that is easy to use. I'm also open to any other features or options that you may have to suggest.
